My molly has had 3 broods this year. She's getting pretty old so I dont know how many more she will have, but it looks like she will have at least 1 more. Her last brood was HUGE and I ended up with 60 babies to care for.
One part I dont like is that she always mates with an orange balloon belly and the babies end up looking wierd. The other part I hate is the fact that I cannot care for that many fish. I ended up feeding most of them to my tiger barbs and my sons cichlids and Jack Dempseys.
